[PATCH] add numa node information to struct device

2006-12-07T16:39:22Z

For node-aware skb allocations we need information about the node in struct net_device or struct device. Davem suggested to put it into struct device which this patch does. In particular: - struct device gets a new int numa_node member if CONFIG_NUMA is set - there are two new helpers, dev_to_node and set_dev_node to transparently deal with the non-numa case - for pci devices the node-info is set to the value we get from pcibus_to_node. Note that for some architectures pcibus_to_node doesn't work yet at the time we call it currently. This is harmless and will just mean skb allocations aren't node-local on this architectures until the implementation of pcibus_to_node on these architectures have been updated (There are patches for x86 and x86_64 floating around) [akpm@osdl.org: cleanup] Signed-off-by: Christoph Hellwig Cc: Christoph Lameter Cc: Greg KH Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

driver core: Use klist_remove() in device_move()

2006-12-01T22:52:02Z

As pointed out by Alan Stern, device_move needs to use klist_remove which waits until removal is complete. Signed-off-by: Cornelia Huck Cc: Alan Stern Signed-off-by: Greg Kroah-Hartman

driver core: Introduce device_move(): move a device to a new parent.

2006-12-01T22:52:01Z

Provide a function device_move() to move a device to a new parent device. Add auxilliary functions kobject_move() and sysfs_move_dir(). kobject_move() generates a new uevent of type KOBJ_MOVE, containing the previous path (DEVPATH_OLD) in addition to the usual values. For this, a new interface kobject_uevent_env() is created that allows to add further environmental data to the uevent at the kobject layer.

driver core: Introduce device_find_child().

Driver core: Call platform_notify_remove later

2006-12-01T22:52:01Z

Move the call to platform_notify_remove() to after the call to bus_remove_device(), where it belongs. It's bogus to notify the platform of removal while drivers are still attached to the device and possibly still operating since the platform might use this callback to tear down some resources used by the driver (ACPI bits, iommu table, ...)
